1991-1996 Chevy Impala/Caprice/Roadmaster Radiator with Fans for LS and LT Swaps
When dropping an LS or LT powerplant into a '91 to '96 Impala automatic chassis, maintaining coolant and transmission temperatures without trimming the frame can halt progress; the 1991-1996 Impala Radiator (Auto Trans) with Fans mounts directly to B-Body rails using OE bracket points and aligns with factory automatic transmission plumbing to avoid adapters and cutting. Its precision TIG welded aluminum tanks integrate with a high efficiency core for quick heat rejection and natural corrosion resistance while keeping overall unit weight low. The pair of dual electric fans are prewired for easy connection to the factory harness and deliver stable airflow at idle as well as in stop and go traffic to prevent heat soak around the engine block. By preserving factory hose port locations and shroud clearances, this radiator system guarantees a trouble free install in Impala, Caprice and Roadmaster models without additional fabrication or trial fits.
Precision TIG Welded Aluminum for Enduring Strength
The radiator uses precision TIG welding to fuse tanks and core plates, creating uniform welds that resist leaks under vibration and thermal cycles common in LS and LT engine swaps. This method avoids filler contamination and produces strong joints that retain pressure over years of service. High quality aluminum offers natural corrosion resistance and excellent thermal conductivity while keeping weight low. Local production under strict quality control includes weld inspection and pressure testing to ensure each unit meets performance standards before delivery.
Efficient Dual Electric Fans with Direct Harness Connection
The dual fan assembly delivers a steady stream of cooling air through the core at idle and in city traffic, preventing heat soak around the engine block. Each fan motor is equipped with sealed bearings for durability and is prewired to mate directly with the factory harness, eliminating the need for extra relays or splices. By operating on demand via the existing coolant temperature sensor, the fans only run when needed and reduce mechanical load by replacing the belt driven unit. Quiet operation and confirmed clearance within the factory shroud preserve engine bay space and minimize noise while ensuring consistent cooling under varied driving scenarios.
Direct Fit to 1991 to 1996 B Body Frame Rails
Specifically engineered for 1991 to 1996 Chevrolet Impala, Caprice and Buick Roadmaster models with automatic transmission, this radiator mounts directly to the original B Body rails using OE bracket locations. Factory hose ports and shroud clearances remain unchanged so there is no trimming or adapter plumbing required to attach the transmission cooler lines. Maintaining the intended coolant flow path avoids hotspots and ensures uniform temperature distribution across the entire core. Development included 3D scanning of the chassis rails to validate fitment and reduce installation time for professional builders and enthusiasts alike.
Coating Options for Protection and Appearance
Opt for the natural bare aluminum finish to maximize radiant heat rejection and reveal the metal's polished texture, or choose the black epoxy coat to enhance corrosion resistance and guard against road debris. The black coat is applied with a two part polyacrylic process that bonds tightly to the surface and resists flaking during repeated heating cycles. A clear sealant layer prevents oxidation in both finishes, and a UV stable additive in the epoxy prevents fade in direct sunlight. These options let builders balance cooling performance and aesthetic preferences without compromising core efficiency.
